Fake Twitter Accounts

This article was interesting to me.  If somebody can make a fake twitter account and have people believe that it is the person they are portraying to be, just think of all of the other types of fraud that are more serious.  It is not just twitter where people are making fake accounts, but face book and myspace too.  It is something that we cannot really control or prevent.  But if fake twitter accounts scare people, then they should be focusing on the real problem; fraud.
